[0001]

[Industrial applications]

 The present invention relates to a deodorizing material made of a flocked sheet in which activated carbon fibers are flocked on the surface of a sheet-shaped base material.

[0002]

[Prior art]

 Generally, there are some deodorants that utilize physical properties and those that utilize chemical properties. When used for deodorization, these deodorants are used alone or in appropriate combination.

Activated carbon typified by activated carbon is known as a deodorant utilizing physical characteristics. This activated carbon is generally in the form of powder or particles, and it is attached to the surface of a honeycomb filter such as when it is used directly as it is when it is used in a cigarette filter or when it is used in an air cleaner. It may be used as a mixture with the filter forming member.

On the other hand, fibrous activated carbon is also known, and such activated carbon fiber has a far superior gas adsorbing function as compared with granular activated carbon. It has the advantage of being large. In particular, polyacryl-based activated carbon fibers containing a nitrogen element as a constituent element have excellent adsorption and decomposability for odorants.

Such an activated carbon fiber is used as a flocking sheet by electrostatically flocking a base material made of paper, cloth, plate, net or the like, as disclosed in Japanese Patent Publication No. 57-31453. It is used as a deodorizing material by cutting it into a predetermined size and shape and then adhering it to the required parts such as refrigerators, kitchen equipment, equipment using solvents, etc. with an adhesive.

However, the activated carbon fibers that have been electrostatically flocked can be peeled or broken from the base material relatively easily depending on how they are handled. For example, the base material is a flexible sheet such as paper, cloth, or film. When the flocked sheet is made of sheet-like material, the activated carbon fiber is deformed by the flocked sheet or the activated carbon fiber is pressed against the pedestal when cutting the flocked sheet or applying an adhesive on the back surface. There is a problem in that the deodorizing function is impaired due to the inconvenience of peeling and breaking. Even when the base material is made of a relatively hard semi-rigid material such as a synthetic resin plate, peeling and breakage of the activated carbon fiber are still unavoidable, although they are somewhat less than those of the flexible material.

[Problems to be solved by the device]

 An object of the present invention is to obtain a deodorizing material composed of an activated carbon fiber flocked sheet, which can be easily and surely adhered to a predetermined site without peeling or breakage of the activated carbon fiber.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the deodorizing material of the present invention is characterized in that an active carbon fiber is electrostatically flocked on the surface of a sheet-shaped base material which is formed in a predetermined shape by applying an adhesive to the back surface in advance It is what

[0009]

[Action]

 Since the deodorizing material is formed in a predetermined shape in advance and the adhesive is applied to the back surface of the deodorizing material, the deodorizing material can be adhered to the predetermined portion only by peeling the release paper attached to the back surface. Therefore, since it is not necessary to cut a wide flocked sheet or to apply an adhesive to the back surface at the time of bonding, peeling or breakage of the activated carbon fiber due to these operations does not occur.

【Example】

 Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1 and FIG. 2, 1, 1, ... Are deodorizing materials composed of activated carbon fiber flocked sheets. The odorant 1 is obtained by electrostatically planting activated carbon fibers 3 on the surface of a sheet-shaped base material 2 which has been coated with an adhesive 4 on the back surface in advance and formed into a predetermined shape. A wide release paper 5 common to the deodorizing materials 1, 1, ... Is attached. Of course, release papers having the same shape and size as those of the deodorizing materials may be individually attached.

The material, thickness, length, flock density, etc. of the activated carbon fiber 3 are not particularly limited, but for example, a polyacryl-based nitrogen-containing activated carbon fiber containing a nitrogen element as a constituent element. Using a fiber having a thickness of 7 to 15 μm and a fiber length of 0.5 to 5 mm, preferably about 1 mm, which is vertically planted on the base material 2 at a density of about 5 × 10 ⁴ fibers / cm ^2. Good to do.

The above-mentioned polyacrylic nitrogen-containing activated carbon fiber has a thickness of 7 to 15 μm, and has about 20 billion micropores having an average diameter of 20 to 40 liters per cm. The adsorption function reaches 10 to 20 times that of granular activated carbon. Therefore, by implanting such activated carbon fibers on the base material 2 at a high density as described above, the outer surface area of the flocked surface can be made very large, and the deodorizing function as a deodorizing material is dramatically improved. Can be improved.

As the base material 2, a soft or semi-rigid material such as paper, a synthetic resin sheet or film, and cloth can be used, and activated carbon fibers can be planted on the base material 2. After the base material 2 is die-cut into a predetermined shape, the adhesive 4 is applied to the back surface of the base material 2 and the release paper 5 is attached thereon, electrostatic flocking is performed by a known method.

As the adhesive 4, depending on the place of use and the conditions of use of the deodorant material 1, a type having a strong adhesive force, a type having a relatively weak adhesive force, or peeled from the adhesive site It is sometimes desirable to use a removable adhesive that does not leave adhesive on the area.

The die cut shape of the base material 2 is arbitrary, and a rectangular shape is shown in the illustrated embodiment, but other polygonal shapes or circular shapes are used depending on the place of use and the use conditions of the deodorant material. Alternatively, it can be formed into any arbitrary shape.

The deodorizing material 1 having the above structure is used by peeling it from the release paper 5 and adhering it to a predetermined portion. At this time, since the deodorizing material 1 is formed in a predetermined shape in advance and the adhesive 4 is applied to the back surface thereof, the peeling paper 5 is simply peeled off as described above, so that the deodorizing material 1 can be easily and securely attached to a predetermined portion. Can be glued to. Therefore, it is not necessary to cut a wide flocked sheet or to apply an adhesive to the back surface at the time of bonding, and the activated carbon fiber 3 is not peeled off or broken due to the work.

The deodorizing material 1 is mainly used for preventing odors such as food in refrigerators and kitchen equipment, adsorbing ozone in OA equipment such as copiers and printers, and volatile solvent odors during cleaning, processing and coating. Prevention of leaks, deodorization of rooms and corridors in hospitals, nursing homes, houses, etc., deodorization of shoe boxes, deodorization of pet sheds, deodorization of cars, etc. The deodorizing material is used by adhering it to an appropriate portion of.

When the deodorizing material 1 cannot be adhered to a wall or other fixed position on a facility, or when it is used in a room such as a hospital, a nursing home, or a house, the deodorizing material 1 is used. It can also be used by holding it on another holding medium. As such a holding medium, for example, a balloon containing helium gas is preferably used, and the deodorizing material 1 is directly adhered to the balloon or is adhered to a medium such as a sheet held by a method such as hanging on the balloon. However, by floating the balloon in the room in that state, the deodorant material 1 can be easily moved to a desired place or a position where it does not get in the way. A deodorizing effect can be obtained. In addition, the deodorizing material 1 can be carried or adhered in an appropriate case with holes and can be carried, and it can be effectively used for deodorizing by putting it in a pocket or bag of clothes. You can

[Effect of device]

 As described above, according to the present invention, the deodorizing material is formed by applying the adhesive to the back surface in advance and electrostatically implanting the activated carbon fibers on the surface of the sheet-shaped substrate formed in the predetermined shape. Therefore, at the time of its use, it can be easily and surely adhered to the specified position simply by peeling off the release paper attached to the back surface.As a result, a wide flocked sheet can be cut into a specified shape or turned inside out during use. Since it is not necessary to perform work such as applying an adhesive while pressing the activated carbon fiber against the pedestal, the peeling or breakage of the activated carbon fiber due to such work is advantageous.
